简言之，影响复合季节的气候变化也是环境湿度和温度两大指标的变化：具体来说，春夏季，特别是雨季，空气相对湿度较大，甚至可以达到饱和，而秋冬季，空气干燥，湿度小；在气温方面，夏季比冬季高得多，两者之间的更大差值可以接近30～40℃（以南方地区为例）。
In short, the climate change that affects the composite season is also the change of two major indicators of environmental humidity and temperature: specifically, in spring and summer, especially in the rainy season, the relative humidity of the air is relatively high, or even saturated, while in autumn and winter, the air is dry and the humidity is low; In terms of temperature, the temperature in summer is much higher than that in winter, and the greater difference between the two can be close to 30-40 ℃ (take the southern region as an example).
如果不注意这些差异，在配制时可能会遇到以下问题：空气潮湿时，胶往往不能完全固化，即不能完全干燥，残余粘度大、严重，甚至在剥离复合膜时会出现拉丝现象，特别是当薄膜本身具有很强的吸湿性时，例如尼龙膜用于复合时，这种现象更为简单；其次，潮湿的空气会凝结在胶辊上，从而将水带入胶盆。随着时间的推移，胶水会逐渐变得混乱和白色，从而失去粘合效果。

If we don't pay attention to these differences, we may encounter the following problems: when the air is humid, the adhesive can't be completely cured, that is, it can't be completely dried, the residual viscosity is large and serious, and even there will be wire drawing phenomenon when stripping the composite film, especially when the film itself has strong moisture absorption, such as when nylon film is used for composite, this phenomenon is more simple; Secondly, the humid air will condense on the cots, thus bringing water into the rubber basin. As time goes on, the glue will gradually become confused and white, thus losing the bonding effect.
高温和潮湿也使胶水难以保存。如果工作胶没有在同一天用完，它往往会变成白色并凝聚成凝胶（果冻）凝胶。相反，当冬季寒冷时，以前未用过的工作胶在一夜之间仍会粘附到优异的透明流动性，甚至可以直接在机器上使用，而不必在新制备的工作胶中分批混合。另一方面，在冬季温度较低时，胶水会变稠，流动性降低。当覆膜机高速运转时，大量气泡简单地堆积在胶水表面和上胶网纹辊边缘。此时，可能会有气泡转移，由于胶量不足，可能会影响复合牢度。
High temperature and humidity also make it difficult to keep the glue. If the work glue does not run out on the same day, it tends to turn white and coagulate into gel (jelly) gel. On the contrary, when the winter is cold, the previously unused adhesive will still adhere to the excellent transparent fluidity overnight, and can even be used directly on the machine without batch mixing in the newly prepared adhesive. On the other hand, when the temperature is low in winter, the glue will thicken and the fluidity will decrease. When the laminating machine runs at high speed, a large number of bubbles simply accumulate on the glue surface and the edge of the roller. At this point, there may be bubble transfer, due to the lack of glue, may affect the composite fastness.
同时，由于复合膜的平整度和松弛性能差，复合膜的外观也较差。例如，胶水的流动网纹比较明显，有时呈桔皮状，当用于层压时，如果印刷表面有大面积的白墨或浅色墨，则在铝箔或铝涂层结合时更容易形成小白点和斑点；否则，由于冬季气温较低，养护室的温度与外界环境温度相差很大。如果保温方法不到位，热损失率远远快于高温夏季，这往往使养护室内的温度达不到设定温度（一般为50摄氏度）。因此，催熟效果也受到一定程度的影响。在同一成熟期，复合牢度可能低于夏季。
At the same time, the appearance of the composite film is poor due to the poor flatness and relaxation properties of the composite film. For example, the flow pattern of glue is obvious, sometimes orange peel. When it is used for lamination, if there is a large area of white ink or light color ink on the printing surface, it is easier to form small white spots and spots when the aluminum foil or aluminum coating is combined; Otherwise, due to the low temperature in winter, the temperature of the curing room is quite different from that of the external environment. If the heat preservation method is not in place, the heat loss rate is far faster than that in high temperature summer, which often makes the temperature in the maintenance room less than the set temperature (generally 50 ℃). Therefore, ripening effect is also affected to a certain extent. At the same maturity stage, the composite fastness may be lower than that in summer.
